Abstract

A Gram-negative, non-flagellated, motile by gliding, aerobic rod, designated DPG-24, was isolated from seawater of Geoje Island in the South Sea, Korea. Strain DPG-24 grew optimally at 30–37 °C, at pH 7.0–7.5 and with 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DPG-24 belonged to the genus and clustered with UST030701-295 and 022-2-26. Strain DPG-24 exhibited 97.6 and 95.8 % 16S rRNA gene sequence similarities with UST030701-295 and 022-2-26, respectively, and 92.4–95.7 % with other members of the genus . Strain DPG-24 contained MK-6 as the predominant menaquinone and iso-C G, iso-C and iso-C 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified lipid, one unidentified aminolipid and one unidentified phospholipid. The DNA G+C content was 36.7 mol%. DNA–DNA relatedness between the isolate and JCM 12885 was 10.8 %. The differential phenotypic properties and phylogenetic and genetic distinctiveness enabled strain DPG-24 to be differentiated from recognized members of the genus . On the basis of the data presented, strain DPG-24 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed; the type strain is DPG-24 ( = KCTC 23502  = CCUG 60798).
